Specicaton of Letters .Patent,l Patented `llltiy Application led March 10, 1915. Serial No. 13,448.

To all 'whom t may concern Be it known that I, CLINTON A. HAGA- noNE, a citizen of the United States, resid ing at Western Springs, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in Coin-I-Iarvesters, of which the following is a full, clear, and exact specification.

This invention relates to corn harvesters of the class in which ears of corn are snapped' from the stalks and husked.

In corn harvesters, such aspickers, there are many parts to be driven.` To drive allv of the necessary parts in an efficient manner, to use as few power transmitting connec` tions as possible, using the minimum amount of power, to simplify and lighten the whole construction consistent with strength and durability, and to constructthe various parts of a corn picker to best cooperate with other parts, are matters of vital importance in the design of corn pickers.

While some corn pickers are good in certain respects, they have fallen short in other respects to meet the requirements for successful commercial operation. p

Accordingly, the objects of `my invention are to simplify and lighten corn pickers, improve the driving mechanism in a manner to reduce the number of transmission parts, and to require the minimum amount of driving power, and tof improve the construction and operation (if-various coperating parts of the picker to obtain the most eiiicient results.

These and other objects are accomplished by means of the corn picker construction illustrated onthe accompanying sheets fof drawings, in which- Figure 1 is a side elevation of a corn picker embodying my invention; p

The various novel features Iof my inven`y tion `will be apparent from the following den scription and drawings, and will be Jparticularly set forth in the appended claims.-

I have illustrated my invention in connec` tion with acorn picker having the usual grainward wheel`10 and stubbleward wheel 11, which are mounted 'upon anv axle 12, keyed to which are sleeve members 13 and 14, to the former ofwhich is Asecured the` main frame supporting member 15 (Figs. 1,

7 and 12). This corn picker isV provided with the usual coperating snapping rolls 16, which are rotatably mounted and supported by supplemental frame members 17,A which are connected to the grainward gathering board 18, which supports theusual grainward gathering chains 19, the stubbleward gathering chain 2O "(Figs. il and l5) 'being supported on the stubblewai'dgather ting! shaft 27,; and a seeenidarypower tirannie#vr f corn picker, most of which include extremely complicated and extremely numerousoper# ating connections. It is one of the objects of my'invention to simplifythe driving c0n nections'to the various parts of a corn picker,

In this connection I have shown what I con- SiderV tov be the preferred arrangement, in

which I have the primary power transmitting shaft 27 kdriven from two large sprocket wheels 29 and 30 rotatably mounted with the grainward andstubbleward wheels, respec tively, said sprocket wheels being engaged by chains 3l and 32, respectively, which pass around sprocket wheels 33 and 34, respectively, both of which are rotatably secured to the` primary power transmitting shaft 27. Sli'dably Ymounted upon and keyed to the primary power transmitting shaft'27 are two spring-pressed clutch members 35 and 36, whichare operatively connected by' a lmember 37, Yto which is secured an arm 38 connected to a bell crank lever 39 by a link 40 `(Figs. lv and 2), the bell crank being connected by a link 41 to a controlling lever 42 near .the operators seat 43. VAs shown in Figs. 2 and 3, the clutch' members 35 and 36 Vare in engagement with the sprocket wheels 'Y 33 and 34`for transmitting power to the primary power transmitting shaft 27. These clutch members 35 and 36, however, may be withdrawn from engagement with the sprocket wheels 33 and 34 to prevent transmission Qf power from the wheels lO'and l1 by depressing the control lever 42, thereby causing a relative movement between the cooperating cam members 44 and 45, which causes the withdrawal of the clutch members 35 and 36 against the action of the, springs 46, the springs 46 returning the clutch members intoV engagement with the sprockets 33 and 34 for again transmitting power to the primary power transmitting shaft when the cont-rol lever 42 is released.

It will be noted that the primary power transmitting shaft is provided with four lixedly secured bevel gears 47, 48, 49 and 50, each meshing with corresponding gears 471, 481, v491, and 501, mounted upon one of eachof the pairs of husking rolls 24, said husking rolls being providedwith the usual intermeshing gearsV 5l, by mea-ns of which the other husking roll of each pair is rotated through the actuation ofits corresponding husking roll. It is seen, therefore, that the husking rolls are driven directly from the primary powertransmitting shaft 27.

For actuating the agitators 52 and beaters V53 over the husking rolls, the following driving connection is'provided: .Mounted inte` grally with the gear 47 on sha-ft 27 is a sprocket wheel 54 (Figs. 2 and .3 'and 13,),

`secondary power transmittingshaft 28 is 'anotherv sprocket wheel 57, around which over which passes. a chain 55, which also passes around a sprocket wheel 56 mounted upon the secondary power transmitting shaft 28.1`At'ithe stubalewgujdjend of the passes a chain 58, which also passes around a sprocket wheel 59 mounted on a rotary shaft 60 (F which is provided with a plurality of beaters 53 for the purpose of pushing back the ears vof corn up `the inclined husking rolls in order to prevent serious crowding or jamming of the ears at this part of the husking rolls. Suitably connected` to the shaft 60 lis a crank or eccentrically `arranged member 62, to which is con,- nected alink 63, which is connected in turn to one of a series of oppositely arranged arms4 64 secured to a. shaft 65, this shaft being given an oscillating reciproeatory movement through the. `action of the rotating Ycrank or eccentric member 62. This recip- `to draw the ears of corn forwardly with respcct to the huskingrolls, and at the same time cause the ears of corn to be alined in a parallel relationship with the husking` rolls. Should an ear .of corn bridge the ltoothed plates on adjacent agitators, the ear would be thrust forwardly instead of rearwardly to obtain the desired results.

At this point I desire to describe my supplemental. forwarding devices, which are mounted. on the lower edges of the agitators 52. These ear forwarding devices include spring-pressed pivotally mounted members 69v (Figs. 7 to Il), which are mounted in plates 70 secured to the under side of the agitators 52. It will be; noted that those ear forwarding members 69 are pivotally 115 mounted in depressed portions or pockets 7l of the members 70 so that the ear forwarding members may be lfreely movable between the members 70 and agitators 52 or into the pockets 7l. 'One end of a spring 72. 120 engages a struck up portion or projection 73 on each of said ear forwarding members 69, the opposite end of the spring 72 beingl stationarily fastened to the member 70, the spring normally hold-ing the ear fornutrdingr members out over each pair of husking rolls 24. and into the paths of movement of the ears` of corn. As shown in Fig. lO, it will bve-noted that outward-movement of the ear forwarding member 69 is limitedrby engage- 130 ment of coperating stop port-ions 741 formed on the heel of each of these forwarding members and a shoulder portion 75 of each of the members 70. These ear forwarding members 69 are so arranged that when the agitators are forced rearwardly, said ear forwarding members 69, moving with `the agitators, will move undercover intottheir pockets if they pass into `engagement with an ear of corn." However, upon the return movement,or forward movement ofthe agitator,\the pointed portion 76 of each of the ear forwarding members will engage thev ears of corn in its path of movement, thus forcing the ears forwardly and `dovsfnw'ardly over the chute77 into the elevator 78. It happens at times that an eari of corn becomes lodged in or around the forward ends of the husking rolls near the elevator, and by providing these ear forwarding members at the forward ends of the agitators 52 in and around parts where the corn has a tendency to become lodged, such ears of corn are forcibly ejected from any lodged position and pushed into the elevator, thus maintain-` ing a clear and free passage for ears of corn from the husking rolls to the elevator. Intermediate the beater shaft 60 and the re-` ciprocatory shaft is a support 79, upon which are pivotally mounted `a plurality of depending ear retarders 80 to insure each ear of corn coming in contactwith the husking rolls so that the husks may be removed from suchears. The general arrangement of the a`gi tators,`ear forwarding device and beater, and their operative connections from the driving source having been considered, driving and power transmitting connections of associated partswill be described.`

Consideration will now be given to the means and connections for driving the endless ear conveying chain 81 (Fig. 6), which has thexproper wings 82 for engaging the ears of corn as they are snapped from the stalk by the snapping rolls 16 and thrown over into the path of movement of the traveling wings 82. The driving and transmission connection to this ear conveying chain includes a bevel gear 83 mounted on and securedrto one end of the secondary power transmitting shaft 28, said gear meshing with another bevel gear 84 i'nount'ed on one end of a shaft, on which also is mounted a sprocket `wheel 85, over which passes the ear conveying chain 81. Mounted adjacent the sprocket wheel 85, 0r formed integrally therewith, is a clutch member 86, which has a releasable connection with another` clutch member 87, which is yieldingly held against the former clutch member 86 by "a 's )ring 88. If, for any reason, the chain s ould be caught or held stationary,` the power transmitted to the gear 84 would net canse a breaka e of the chain er `the sa parte., "ne te the fast that the? clutch members 86 and 87 would rotate relative to each other, thereby preventing transmission of motion to the chain 81. It is seen, therefore, that the `driving connection from the secondary power transmitting shaft and, indeed, from the primary power transmitting shaft to the ear conveying chain 81, is simple and includes a minimum number of parts, taking other coperating parts `of the machine into consideration. `As stated before, the ears of cornare conveyed from theisnapping rolls to the husking rolls by this ear conveying member.` The 1. husks which are removed from the ears by `the husking rolls are droppeddownwardly upon afhusk conveyer 89. u

This` huskconveyer 89 receives its motion through the following connections including a sprocket wheel `90 mounted upon the secondary power transmitting shaft 28, a chain 91 (Figs.` 1 and 2) passing over said sprocket wheel and also over another sprocket wheel 92 mounted upon a shaft 93, which is suitably supported in bearing mem-` bers `94connected to the frame by links 95. Mounted upon a shaft 931, operatively 4connected; through suitable gearing with shaft 93, are sprocket wheels which cause movement t'o be transmitted to the husk conveyer through chains 96 forming a part of such conveyer, the husk conveyer lying below the husking rolls in a manner to catch all of the husks dropped therefrom, and also loosened kernals of corn,`the latter of which pass forwardly into the elevator 78 through a suitable chute 97. On one end of the shaft 931 is a sprocket wheel 98, over which passes a chain 99, which also passes over a sprocketI wheel 100 mounted on a shaft 101 (Figs. 1 and 7) suitably ,supported below the main frame member 15, said shaft having secured thereto gear connections to a. bevel gear .102 mounted on one end of a shaft 108 for driving the elevator conveyer belt 104 (Fig.v 12), there being a suitable clutch 105 for controlling the connection between the shaft 103 and theelevatorconveyer chain 104i. It is seen, therefore, that the husk conveyer 89 is driven from` a chain passing over a sprocket wheel on the secondary power transmitting shaft, and that the eleva-tor conveyer104 isdriven from the husk conveyer shaft through the chain 99 and shaft 103. i Y

, The driving connections for transmitting motion to the snapping rolls `will now be considered. It will be noted that the hori-` zontal primary power transmitting shaft 27 extends `completely across the rear of the machine and is provided with a universalv connection 106 to avoid any cramping should there be a tendenc for the parts of the shaft to getout of a mement. At oneend ef this primary power transmitting shaft?! there secured arelatasel .ler-,ga

ist

transmitted to thel other Y pin-g rolls 16 are Vdriven directly from the primary power transmitting shaft through the shaft 109, which, as a-matter of fact, might be considered a part` of one of the snapping rolls. This shaft 109 extends rearwardly, and near its. rear end is provided with a sprocket wheel 111, over which passes a chain 112, which also passes over a sprocket wheel 113 mountedupon one end of a short shaft 1111, to which is secured a bevel gear V115 meshing .with another bevel gear 116 mounted upon `oneV end ofa shaft supporting one of the trash rolls 117, the other trash roll 118 being driven from the first trash roll through intermeshing gears'119. These vertical trash rolls are arranged at rightV angles with respect to primary shaft 27 and snapping rolls 16, andare located at Vthe rear end ofthe passage leading from Vthe main Y a 'suitable shaft through which all of thev snapping-'rolls 16-and ear conveying chain 81'. yThe function of this pair of trash rolls isl to removev all Vtrash from the machine and to V snap the Vears off of broken portions of stalks or protruding ends of long stalks which'have passed upwardly inthe machine, these rollspreventingrthe trash and stalks' from being passed on into the husking chamber, and passing said'trash and stalks outwardly at the rear end vof the machine. It is to be noted that the snapping and trash rolls are driven from the primary power transmitting shaftf2?` through the large bevel gear 107 Y SeV far as the power transmitting connections aire concerned, there remains but -one to Vbe considered. vThis connection is the one by means of which the gathering chains are driven. f

Adjacent the relatively large ybevel gear 107 on the'prifmary power transmitting shaftV 27 is a sprocket 120 (Fig. 1'), over which passes a chain 121, which also passes overl a sprocket wheel 122 secured to a shaft 123. Mounted on this shaft 123 is a bevel gear 124-,v with which meshes another bevel pinion 125 mounted` upon one end of a shaft 126, at the other` end of which -is a bevel gear'127 meshing with a bevel gear 128 mounted upon gatheringv chains 19 on the grainward side of thermachine are driven. Also mounted upon the shaft 123 (Fig. 4) is a sprocket wheel 129,;over which passesV a chain 130 for driving the stubbleward gathering chain through suitableconne'ctions 131. It is seen,

' therefore, that power is f transmitted :from

the primary power transmitting shaft tothe g sidered hereinabove in detail.

The operation ofthe machine in brief is asfollows: `Stalks bearing earsof corn arc engaged by the snapping rolls 16 during the forward travel of the corn picker, the ears being snapped from the stalks and caused to be passed into the 'path f of movement of wings 82 of ear conveyers 81, which cause the ears to be conveyed from the innnediate vicinity of the snappingrolls past the trash rolls, where any trash or stalks which have been permitted to pass will be withdrawn, the ears being forced on by the ear conveyer to a point where the ears are deposited into the husking chamber and are treated by the husking rolls, the husks being removed and deposited upon the husk conveyer 89, which discharges rearwardly of the machine. At the saune time the ears of corn in the husking chamber are agitated by the agitators 52 and caused to take a parallel position with regathering chains through connections eenspect to the husking rolls regardless of the position which they may assume 1n passing into the huski'ng chamber. The ears are prevented from packing by the. beaters 53, and areV retarded in their downward movement by the earretarders 80, which cause all of the ears to be treated by the husking rolls. The-ears are forwarded and 'prevented from becoming lodged and wedged at the lower Vand forward'ends of the husking rolls by the auxiliary ear forwarding members 69, which canse the ears to be forced down over the chute 77 into the elevator 78, by means of which the ears are conveyed upward by thev elevator conveyer 104e into a wagon, which may be drivenl alongside of the corn picker. v

The number of power transmitting connectionsl to the various parts have been reduced to the minimum and are arranged to use the smallest amount of power, and the various elements of the corn picker have been designed to so eoperate with each other as to -produce the most eiicient results. It will benoted that power is received directly from the main wheels 10 and 11 by the primary power transmitting shaft 27. From this primary power transmitting shaft 27 the husking rolls and snapping rolls are driven directly. The trash rolls are driven directly from this primary power transmitting shaft through the shaft 109, and the gathering chains are driven from this main power transmitting shaft through a chain 121. It will be noted also that to the rear of the main power transmitting shaft 27, and parallel therewith, is the secondary power transmittingshaft 28 driven directly from the shaft 27. From this secondary power transmitting shaft the beaters and agita-tors are actuated through a chain 58. The husk conveyer 89? operated from this secondary pawer ftransmittlng shaft 28 through a cham- 4said shield plate,

91, and the elevator isdriven from the shaft ofthe husk conveyenwAlso from this secondary power transmitting shaft 28 the corn conveyer 81 for conveying the l corn from the snapping rolls to the husling rolls is driven, directly through intermeshing gears, 83 and84, the formerof which `is mounted directly upon the secondary power transmitting shaft. This compact driving arrangement, including 4all of the various parts, is arranged to produce the most eifrcient results. e
